(/4445; 4% arrfz bmw m A TTORNEY TRANSPOR'IABLE PREFABRICATED BUILDINGSTRUCTURE WITH CANTILEVERED ROOF TRUSSES BACKGROUND OF THE INVENTIONgreatly hampered by the problems of transporting the finished buildingto the final location without the costly procedures of handling thebuildings without stress and strain. Thus, a great deal of finishingwork had to be finallydone on the job location because of the stress andstrains to which the building was subjected during moving, resulting inhigh costs and the defeat of real complete factory production of thebuilding.

SUMMARY OF THE INVENTION One of the objects of this invention is-toprovide a structurally sound house of conventional size and appearanceat a minimum of cost.

Another object is to provide the combined permanent structure of thebuilding and the structural requirements of transporting the buildingthrough itsrnanufactun'ng stages, transportation, and the placement ofthe building on its permanent support piers as one and the same whereinconsiderable time and expense is saved.

It is a further object to accomplish the combined structuralrequirements with a minimum weight, material and expense and to do thisin keeping with acceptable architectural design.

DESCRIPTION OF THE PREFERRED EMBODIMENT As an example of one embodimentof this invention, there is shown a building structure comprising twolongitudinally extending parallel structural trusses 10 and 11 havingtheir outer ends extending beyond the front end 12 and the rear end 13of the house proper, these projecting ends providing room for installingconveyor'wheels or other devices for the transportation of thebuilding..The structural trusses 10 and 11 may be bowstring laminatedbeams or any other type of truss of suitable design to carry therequired load.

The structural trusses are provided with upwardly extending studs whererequired to support the laterally extending roof trusses 15 and aresecurely fastened to the structural trusses l0 and 11, and are ofsufficient size and design to carry the roof load of the roof 16, thefront wall 12, the rear wall 13, the sidewalls 17 and 18, and the floorl9. The outer wall sections 12, l3, l7, and 18 are securely fastened toand suspended from the roof trusses l5, placing the outside wall studs20 in tension. These tension wall studsmay be incorporated with suitabletension rods or other suitable apparatus to insure adequate strength.The floor joists 21 are hung in places between the lower portions of theouter walls and the structural trusses and securely fastened. The floorjoists may be hung in three sections as shown in FIG. 6, or may be acontinuous joist spanning the total width between the sides 17 and 18 ofthe building or any combination of the same.

The structural trusses l0 and I1 as shown in FIGS. 5 and 7 as extendingbeyond the front and rear of the building proper can be used to supportporches at the front and rear after the building is transported andplaced on its footings or piers, or the truss ends may be cut off asdesired. The structural trusses l0 and 11 may be supported on four ormore piers 22 located so as to distribute loads and in so doingeliminate the necessity for continuous footings and foundations.

The structural trusses l0 and 11 are provided with a plurality oflifting eyes 23, FIG. 8, or similar devices suitably attached as by nuts24 on the rods 25 which can run through the roof trusses 15, the wallsections 26, and through the structural trusses l0 and 11. The purposeof this lifting device is to provide the means to lift and movethe'building with a crane during manufacturing and to place the buildingon the piers 22 at the permanent location. This method is of particularadvantage in uneven terrain and in areas where movement of the buildingon its moving dollies in wet and inclement weather is impractical. Withthis system the complete building can be easily and safely moved withoutdamage from the street to the foundation piers with a crane or othersuitable lifting and carrying equipment.

I claim:

l. A prefabricated building structure comprising in combination:

A. a plurality of longitudinally extending horizontal struc turaltrusses, said trusses being of sufficient strength to support thestructure during transportation, handling and placing on piers;

B. a plurality of laterally extending roof trusses;

' C. vertical studs fixed at their lower ends to the structural trussesand connected at their upper ends to the roof trusses so that the rooftrusses are supported on the structural trusses;

D. outside walls for the building suspended from the roof trusses;

E. floor joists hung between theouter walls and the structural trusses;and

F. lifting means extending through roof trusses, said vertical studs andsaid structural trusses at the junction point of said vertical studswith said roof trusses, and means connected to said lifting meansoutside of said structural trusses to tightly secure said structuretogether, some of said liftin'g means being provided with lifting eyesat said junction point for lifting said structure as a unit.

2. A building structure as in claim 1 wherein the ends of the structuraltrusses extend beyond the outside walls of the buildmg.

3. A building structure as in claim I wherein lifting means compresses arod extending through the roof trusses at the junction point of thevertical studs with the roof trusses and through said horizontaltrusses, and a nut threadably connected to said rod outside of saidstructural trusses to tightly secure said structure together.

4. A building structure as in claim 1 wherein the outside walls aresuspended at their upper edges on the outer portions of the roof trussesand the floor joists are hung from the lower edges of the outside wallsand the structural trusses.

1. A prefabricated building structure comprising in combination: A. aplurality of longitudinally extending horizontal structural trusses,said trusses being of sufficient strength to support the structureduring transportation, handling and placing on piers; B. a plurality oflaterally extending roof trusses; C. vertical studs fixed at their lowerends to the structural trusses and connected at their upper ends to theroof trusses so that the roof trusses are supported on the structuraltrusses; D. outside walls for the building suspended from the rooftrusses; E. floor joists hung between the outer walls and the structuraltrusses; and F. lifting means extending through roof trusses, saidvertical studs and said structural trusses at the junction point of saidvertical studs with said roof trusses, and means connected to saidlifting means outside of said structural trusses to tightly secure saidstructure together, some of said lifting means being provided withlifting eyes at said junction point for lifting said structure as aunit.
 2. A building structure as in claim 1 wherein the ends of thestructural trusses extend beyond the outside walls of the building.
